What is the molarity of sodium sulphate in a solution prepared by dissolving 15.5g in enough water to make 35ml of solution?
Molarity = moles of solute/volume of solution
Find moles NaCl
55 grams NaCl (1mol NaCl/58.44 grams) = 0.941 moles NaCl
Molarity = 0.941 moles NaCl/35 Liters
= 0.027 Molarity NaCl
( sounds reasonable as 55 grams is not much in 35 Liters of water, which would be about 17.5 2 liter sodas )

What colored coating is formed on adding zinc granules to freshly prepared ferrous sulphate solution?
A red-brown colored coating is formed on adding zinc granules to freshly prepared ferrous sulphate solution. This is due to the oxidation of ferrous ions in the solution to ferric ions, which results in the formation of ferric oxide/hydroxide on the surface of the zinc granules.
What is observed when sodium sulphate solution is added to barium chloride?
A white precipitate of barium sulphate is formed when sodium sulphate solution is added to barium chloride solution. This is due to the formation of an insoluble salt, barium sulphate, which appears as a white solid in the solution.
What ions are present in sodium sulphate solution?
Dissolving in water (aq):Na2SO4 --> 2(Na+)aq + (SO42-)aq
What two ways can speed up the rate of dissolving copper sulphate in water?
To speed up the rate of dissolving copper sulfate in water, you can: Increase the temperature of the water: Heat helps to break down the copper sulfate crystals, making it dissolve more quickly. Stir or agitate the solution: Stirring or agitating the water helps to distribute the copper sulfate particles evenly, increasing the surface area of interaction with the water and speeding up the dissolving process.
How will you obtain pure copper sulphate crystal?
boil off the solvent (usually water) until you are left with copper sulfate crystals. For getting back the copper sulphate crystals from copper sulphate solution, we have to first make super saturated solution by boiling, then allow to cool down & dried these crystals with filter paper.
What is the molarity of a solution made by dissolving 23.4g of sodium sulphate in enough water to make up a 125ml solution?
To find the molarity, first calculate the number of moles of sodium sulphate using its molar mass. Sodium sulphate's molar mass is 142.04 g/mol. Next, divide the number of moles by the volume in liters (125 ml = 0.125 L) to get the molarity. This will give you the molarity of the sodium sulphate solution.
How do you make zirconium sulphate solution?
To make a zirconium sulfate solution, dissolve zirconium sulfate powder in water. The concentration of the solution can vary depending on the desired application. It is important to stir the solution well to ensure that the zirconium sulfate is fully dissolved.
How benedict solution prepared?
A Benedict's solution is a solution of sodium citrate, sodium carbonate and copper sulphate, whose colour changes from blue to yellow to red in the presence of reducing sugars such as glucose.
What effect would dissolving some copper sulphate crystals in the water have on its boiling point?
Adding copper sulphate crystals to water will raise the boiling point of the solution, as the dissolved particles disrupt the water molecules, making it harder for them to escape as vapor. This results in an increase in boiling point compared to pure water.
What colored coating is formed on adding zinc granules to freshly prepared ferrous sulphate solution?
A red-brown colored coating is formed on adding zinc granules to freshly prepared ferrous sulphate solution. This is due to the oxidation of ferrous ions in the solution to ferric ions, which results in the formation of ferric oxide/hydroxide on the surface of the zinc granules.
What do copper sulphate crystals form when a hot saturated solution of copper sulphate is cooled?
Copper sulphate crystals form when a hot saturated solution of copper sulphate is cooled down. As the solution cools, the solubility of copper sulphate decreases, causing the excess copper sulphate to come out of the solution and form crystals.
What is observed when sodium sulphate solution is added to barium chloride?
A white precipitate of barium sulphate is formed when sodium sulphate solution is added to barium chloride solution. This is due to the formation of an insoluble salt, barium sulphate, which appears as a white solid in the solution.
What term is used to describe the mixing of copper sulphate and water?
The term used to describe the mixing of copper sulfate and water is "dissolving." When copper sulfate is added to water, it dissolves to form a homogeneous solution where the copper sulfate molecules are evenly distributed throughout the water.
What ions are present in sodium sulphate solution?
Dissolving in water (aq):Na2SO4 --> 2(Na+)aq + (SO42-)aq
What happens when freshly prepared solution of ferrous sulphate followed by conc.H2SO4 is added to nitric acid?
You can obtain the ferric sulphate - Fe2(SO4)3; because the ferrous sulphate react as a reducing agent.
How do you distinguish between copper sulphate solution sodium chloride solution sodium nitrate solution or sodium sulphate solution?
copper sulphate solution-blue sodium chloride (salt) solution-clear sodium nitrate solution- white to clear sodium sulphate solution- white copper sulphate solution-blue sodium chloride (salt) solution-clear sodium nitrate solution- white to clear sodium sulphate solution- white
What is the colour of aqueous solution of ferrous sulphate?
The aqueous solution of ferrous sulphate is typically pale green in color.
